霓(蜺)ní大气中有时跟虹同时出现的一种光的现象。形成的原因和虹相同,只是光线在水珠中的反射比形成虹时多了一次,彩带排列的顺序和虹相反,红色在内,紫色在外。颜色比虹淡。{secondary rainbow, a phenomenon of light that occurs simultaneously with, and for the same reason as, a primary rainbow, but different from the latter in that sunlight is reflected on water drops for one more time, that the colour sequence is reversed, with red on the inside and violet on the outside, and that it is less intense;}也叫also副虹{fùhóng}。参看see‘虹’(hóng)。 |
